| 摘 要： | 沥青稳定碎石基层属柔性结构层，具有很强的柔性和变形能力，作为应力消散层，大大延缓了路面反射裂缝的发生。另外，沥青稳定碎石基层可以与沥青混凝土面层牢固结合，并且由于其模量与面层模量接近，使得路面结构受力更加均匀，从而提高了道路的耐久性，延长了路面的使用寿命。

| Abstract: | Asphalt treated base is a flexible structural course which has strong flexibility anddistortion ability. As a stress-dissipation course, it stays the accruing of pavement reflective crack. In addition, because asphalt treated base can be combined with asphalt concrete surface hard, and its modulus is close to surface modulus, which makes the stress of pavement structure be more symmetrical, thus the durability of road is enhanced and the service life of road is prolonged. |

| Keywords: | asphalt treated macadam flexible base reflective crack service life mix proportion design |
